ReadyNAS Duo V2 No RAID, replace 1 drive
Hello,
I have a ReadyNas Duo V2 for years. I have 2 harddrive in it (1TB + 2TB), there is no JBOD, redudancy, RAID or anything.
What I see on the web page:
ReadyNAS Duo v2
RAIDiator 5.3.13
RAID Type: Flex-RAID
/c RAID 0 (Not-Redundant) 27.2GB Free Of 913.4 GB
/d RAID 0 (Not-Redundant) 40.8GB Free Of 1.8 TB
I have a new 4TB HardDrive.
What is the correct way to use it instead of my 1TB drive (/c) ? Do I have to plug the drive while the NAS is on or off ? Is there an admin page I should access to tell ReadyNAS that there is a new drive and how it should use it ? (RAID ? JBOD ? Just a second drive ?)
I tried to plug it while the NAS is off, the drive is not dectected.
I tried to plug it while the NAS is on, it seems that the NAS decide to use it to be a redundant copy of /d.
It don't want any redundancy, nor JBOD. I just want to have a storage capacity of 4TB and 2TB (instead of 1TB and 2TB today) as 2 differents drives
It would be nice if there is a way to do this without having to erase everything on my 2TB /d drive (I have no extra drive to backup it).
Data from the 1TB drive are backuped on an other drive, no need for a full procedure on "how the change 1TB to 4TB without a backup space" (kind of "replace 2TB by 4TB", "copy 1TB on 4TB", "replace 1TB by 2TB", "done")

With OS 4 or OS-6 you'd destroy the C volume from the admin UI. Then you'd hot-swap the new disk, and create a new volume on it. This wouldn't touch the data on your D volume.
I'm not sure about OS 5 - I never owned one, and the software manual doesn't describe how to delete a volume. Hopefully someone here who does own a v2 NAS (and who uses flex-raid) will be able to clarify.
You could also explore the web ui, and see if you can find a function to delete a volume. Secure erase might work, but I think it would be very slow
Thank you for your fast answer.
I double checked the web admin UI but I don't find a menu to work on volumes. (either the volume is here or isn't)
The only page which looks a bit like what you says (from far) is the "Shares" page where you can add/remove shares. But a Share is a directory on a drive/volume (I can create or delete shared folders, several ones on each volume), it's not the drive/volume that I create or delete.

Welcome to the Community!
It seems that the Duo V2 is not behaving correctly when you try to expand the volume. With Flex-RAID when you add/.expand a new disk it should create another volume with the same configuration as the other volume left. JBOD will create another JBOD, RAID 0 will have another RAID 0.
When you replaced the 1TB drive you mentioned that the 4TB drive was being configured as a redundant copy of /d so the behavior seems to be like X-RAID which is not the case on what you have posted.
Expanding Flex-RAID Volume
There's no option to destroying/deleting a volume on OS 5 unless you are comfortable with SSH there might be a way. So I would suggest doing a Factory Reset to get a fresh set of JBOD disks 4TB and 2TB just make sure you have full backup of your data.
Hope this helps!

This is the key point. Unlike other ReadyNAS, OS 5 just doesn't have the feature you need. So a factory reset is the way forward (painful though that is).
If you expect your storage needs to continue to grow, you might want to get a second 4 TB drive.
You could then go with the normal XRAID. That would give you about 1 TB of free space now, and the option of upgrading both drives later on to increase the volume size - without the pain of another factory reset.
Or you could stick with two volumes and 5 TB free space - perhaps enough storage to last through the life of the NAS.
FWIW, a setup with one volume per disk is generally called JBOD here.
